Does it have caffeine?
Nope. Just clean, natural ingredients that work.
Is vinegar the main taste?
It’s there, but balanced. Bracing and refreshing, the perfect balance of salty, sweet and sour. Think tangy, not vinegary.
What’s hyper-hydration?
When we were creating Posca Hydrate we sent the liquids to labs in the US for osmolality testing. The results that came back surprised us – Posca Hydrate is hypertonic. Your gut will draw the nutrients from Posca into your body faster, along with the vinegar It means we pack a punch: electrolytes + vinegar = faster, longer-lasting hydration.

Yes. We made it for real life – hydrate without regrets.
